The Who, a rock ’n’ roll powerhouse for nearly four decades, is back on the road and playing the Tweeter Center tonight. They’ll perform — just like the last time around — without bassist John Entwistle, who died in 2002 of a drug overdose, and Keith Moon, who died of drug- and drink-related causes back in 1978.

So, is this outfit helmed by Roger Daltrey and Pete Townshend (above, from left) — once called “unwashed, foul-mouthed, booze-swilling no-hopers” by an Australian newspaper — a mere shadow of its once glorious self? Go! says No! We saw ’em post-Entwistle two years ago and they rocked and they roared. (If you have hazy memories of Townshend and that computer child-porn case, remember he was cleared last year.)

Expect to hear “Old Red Wine,” a new tune and tribute to Entwistle, and “Real Good Looking Boy” (another new one), along with the classics. The band mrnorth opens at 7:30. Tickets: $35-$125.

Route 140, Mansfield, 508-339-2333.
